Abstract

Un appareil de remplissage pour poudre reçoit une quantité prédéterminée de poudre provenant d'une trémie à poudre dans un trou de réception aménagé dans une partie périphérique d'une plaque rotative, tourne la plaque rotative de manière intermittente, et évacue la poudre du trou de réception vers un récipient à poudre placé au-dessous lorsque le trou de réception atteint une zone de remplissage où s'effectue la mise en récipient de la poudre. La plaque rotative (1) est disposée de manière à ce que son axe de rotation C soit incliné et chaque trou de réception (8) est réalisé de manière à ce que son axe se trouve sur une surface conique imaginaire (12) ayant un angle de conicité υ de 60° - 120° et un axe qui coïncide avec l'axe de rotation C. La trémie (6) à poudre est disposée sur un côté d'une ouverture (8a) du trou de réception (8) dans une unité aspirante (9) et un essieu (28) supporte un arbre rotatif (34) d'un agitateur (7) au-dessus de la trémie (6) à poudre. Cet appareil convient au remplissage d'un récipient tel qu'un flacon avec différentes poudres, en particulier des médicaments pulvérulents tels qu'une poudre pour injection qui demandent un dosage précis et doivent être protégés de tout mélange avec des corps étrangers.
